1. In order to investigate the development of the fruit of walnuts, the weight and size of the fruit and the chemical composition in its kernel, were observed at the interval of two weeks, using Oni kurumi (Juglans Sieboldiana MAXIM.) and Teuchi-kurumi(J. regia var. orientalis KITAMURA). 2. The growth period in the size of fruits was chiefly found within six weeks after the flowering, while that in the weight was within nine to ten weeks after it. 3. Concerning the chemical composition in the kernel, the soluble non-nitrogen substances which were abundant at the earlier stage, decreased gradually with the fruit growth, but the fat increased rapidly after the fruit reached the maximum weight. Protein increased gradually till the end of the growth.
